New Jessops or Old Jessops
I bought my 40D and 50D from Jessops. 50D came in an opened box, I wasn't happy and asked them to swap for one that still had the seal. (All my cannon cameras have come with a clear circular seal). They did, I got it home, it had a Cheap CF card in with around 200 shots of the store, staff and customers. They'd blatantly just resealed the box with a sticker on a used, demo'd item. When I complained they offered to knock some money off, but I wanted a new item. I got my money returned and went to a local independent.
Or the time I drove an hour to Bath to collect a manfrotto pistol head I wanted, having first called - "yes sir, brand new sealed in box"
As I walk in I notice on the display the item I want is missing, all others are displayed. The item is sealed, but I opened it to check it having been caught out before. Sure enough they'd taken the one from display and resealed it in it's box. Action felt like it had a whole beach in it and the handle was seriously damaged, scratched so much part of the logo was missing. Again they offered a small amount off.
Waste of my time, money and why I never used Jessops again.
There should be no reason why any box is open. If a customer wants to play with an item that's what demo models are for. The customer gets to open the box when it's paid for or they've got the money on the counter.
